Haldia (SC) in Purba Medinipur district is currently represented by Tapasi Mondal of the All India Trinamool Congress (AITC) in the West Bengal Legislative Assembly. She won the 2021 election with 104,126 votes (47.15per cent vote share), defeating AITC's Swapan Naskar (89,118 votes, 40.36per cent) by a margin of 15,008 votes after switching from the BJP during the term. Key issues include urban infrastructure pressure from Haldia industrial township growth, drainage and flood control in low-lying Sutahata CDB areas, and drinking water supply for 22.6per cent SC population. Demand for health facilities, schools, local employment beyond petrochemical plants, and welfare scheme delivery for scheduled castes remains central amid 87.66per cent literacy and rapid urbanisation. Voter turnout exceeded 87per cent with 358 polling stations serving 2.51 lakh electors. Tapasi Mondal's journey—from CPI(M) 2016 win (margin 21,493 votes), BJP 2021 victory, to TMC switch—marks dramatic volatility in this industrial-reserved seat previously held by TMC's Seuli Saha (2011). Haldia falls under Tamluk Lok Sabha constituency, won by BJP's Abhijit Gangopadhyay (2024), creating an Assembly-LS party split. High 90per cent+ turnout historically underscores an engaged electorate balancing industrial jobs, welfare and caste politics.
